400x300 4.2inch E-Ink Display

This is a 4.2inch E-Ink/E-Paper display module with 400x300 pixel resolution, with an integrated controller that communicates via the SPI interface. Due to its extremely low power consumption, it is great for battery-powered applications. These displays are also used in retail as price tags, where they are operated with one battery for several years. The display has a very good viewing angle and can also be easily read in sunlight. A connecting cable is included in the delivery with which you can easily connect the display to a Raspberry Pi. For an Arduino Uno or if you want to plug it into a breadboard, you will need 8 x male/male Dupont cables.

Features: 

• Display records are retained even without power supply
• Onboard level converter thus compatible with 3.3V and 5V microcontrollers
  
• Ultra-low power consumption. Basically, power is only needed for refreshing 
  
• SPI interface for connecting to controller boards such as Raspberry Pi, Arduino, ESP8266 or ESP32
  
• Good documentation and sample code available on Waveshare Wiki
• Programming examples available for the following controllers: Arduino, stm32 and Raspberry Pi

Alternative Libraries for Arduino and STM32:
